BTC: Local Mempool VByte-Weighted Fee Rate — Last Sample

Bitcoin Local Mempool VByte-Weighted Fee Rate — Last Sample was 0.275 sat/vB on 9 Nov 2026 (latest daily value).

Total captured base-fee satoshis divided by total Core policy virtual bytes.

Why use it. Read the fee rate of pending virtual-byte mass rather than the average transaction. How to read it. Larger transactions receive proportionally more weight. This need not equal the transaction mean or median. Empty populations are undefined. The hour/day point is the last actual accepted sample in that UTC bucket, not a time average. Earlier or missing samples and departed/replaced transactions are not reconstructed. Read capture clocks and gap coverage; a final sampling-period label does not confirm its transactions.

Calculation. Use the same verbose Core capture for all fee/size/count inputs. Sum exact base-fee satoshis and policy vbytes from one capture, divide their totals and publish at 40 significant digits, half-even. Fee rates use Core base satoshis / its policy virtual bytes, excluding prioritisation deltas and ancestor/package averaging. Only one local Bitcoin Core node is observed; this is not a worldwide mempool census or a confirmation forecast.
